The 23-year-old Seattle native has been granted a full and independent review of the DNA evidence used to convict her and her former boyfriend, Italian Raffaele Sollecito, in the brutal sexual assault and murder of her roommate Meredith Kercher.

Knox and Kercher, who was from the UK, were both exchange students in Italy at the time of her murder. Knox, Sollecito and another man who was tried separately, were all convicted of her murder.PHOTOS: Celebs Who Have Done Jail Time

Knox, her family and attorney have always maintained her innocence. They’ve insisted the DNA evidence taken from Kercher’s bra and a knife believed to have been used to slit her throat was inconclusive and should never have been seen as compelling evidence.

Amanda’s mom, who has made frequent appearances on the Today show since her daughter’s ordeal began three years ago, cried in open court as the decision was read.

“Finally a little bit of good news,” Edda Mellas said.

Knox’s request for the DNA review had earlier been denied by a lower court; she’s facing 26 years in prison if the conviction stands.
